Dear Rose Mary,
the number of plane waves depends (very weakly) on the k-point, while npwx  
is the maximum among all k-points. If you wish to know the number of pw at  
each point you can edit PW/hinit0.f90 to add a print statement after line  
57, i.e.:
   IF ( nks > 1 ) WRITE( iunigk ) igk !line 57
   write(*,*) "kpt,npw:", ik, npw


best regards
